The final result, $U(\omega) = \pi \delta(\omega) + \frac1i\omega$, is a powerful expression that tells us a great deal about the signal: FH(t)=πδ(ω)+1jωscript cap F the set cap H open

for symmetry, though in many applications, the exact value at the point of discontinuity doesn't affect the integral transform. The Challenge of Direct Integration $U(\omega) = \pi \delta(\omega) + \frac1i\omega$
